Transformation Elastography: Converting Anisotropy to Isotropy

2020 IEEE 17th International Symposium on Biomedical Imaging (ISBI), 2020
Elastography refers to mapping mechanical properties in a material based on measuring wave motion in it using noninvasive optical, acoustic or magnetic resonance imaging methods. For example, increased stiffness will increase wavelength. Stiffness and viscosity can depend on both location and direction. A material with aligned fibers or layers may have

Using convert to transform source code

Software: Practice and Experience, 1979
AbstractThere are a number of reasons why one might wish to transform the source code of an operational program: To make the program conform to a standard layout. To make the program conform to syntax and semantics standards. To improve the performance of the program.

Transformer synthesis for VHF converters

The 2010 International Power Electronics Conference - ECCE ASIA -, 2010
This document presents a method to synthesize an air-core transformer with a given inductance matrix. The proposed algorithm is used to design a two-winding transformer for a Φ 2 resonant dc-dc converter operating in the VHF (30–300 MHz) regime. The method realizes the required inductance matrix to achieve proper tuning while trading volume and ...
